Sure, ok, more divisions could solve the problem, but I believe that the whole experience will become watered down and the champions will become more meaningless as no one will be able to remember nor care for so many names. So I still think that fight days might be a better option.
Only heavyweight in UFC don't have to care about their weight and they can eat and drink whatever they want before fight, just look at that fat beast Derrick Lewis

Bellator is back this weekend with big fight Bellator 266 Davis vs Romero!
We can finally see Yoel Romero debut in Bellator after coming from two loses in UFC and two canceled fights in Bellator.
Romero is much older and slower than Davis who has 5.5 inch advantage in this fight, and this fight might be more interesting than main event in UFC.
